' ing Machines, of which the following is a Yns specification, referencebeing had therein to the aceoinpanyinw drawing.

'My invention relates to button sewmg machines and more particularly tothat-type.

of button Sewing machine wherein a plu* rality of shank-eyed butt-ons(such as shoe battons) are .sewed successively and at spaced apartpoints upon any given article (such as a shoe);

a prior exarnpleof that type of machine which may be referred to forconvenience, being that illustrated in U. S. Patent No. 885,826,patented May 5, 1908.

Among 4the objects of the present irnprovenients are the production of anovel, simple and direct acting machine, one which may operate vat highspeed, and will possess great durahilit)7 and ease andy quietness oitoperation.

Other objects are to provide a special and advantageous means ofactuating the, castol bar which cooperates with the needle, and tosecure a certain coopera-tion with the needle;I also to provide a meansor device for backing u or affording a `support to the sewing` nee lewhile the thread'isunder tension, as for example when the loop is beingspread preparatory to passing it over the button.

.Further objects and advantages in the present'improvements will bedescribed or will he understood in the following speciii cation. v

For convenience I have shown the present improvements as applied to thetype of machine illustrated in vprior latent No. 886,826 before referredto, lin which type of machine a primary thread loop is first formed anddrawn through the ey'e of the button. followed by the formation of a.sec ondar)` loop drawn through the fabricadjacent to the first loop andthen interlocked with the first loop by being drawn through, it,andthereafter"spread over the head of the button; the work beingautomatically fed beween'the formation of the first and,

second loop and betwcen the .attachment of two successive buttons hy awork feeding` spieadcr hai" in cross-sectionmechanism fully shown anddescribed in said prior patent and not per .se forming an)Y part ot' thepresent improven'ients. Y

i will first lescribe an embodiment of the present inun'ofenients andwill thereafter point out the novel features in the claims.

Similar letters of reference designate corresponding parts in theseveral figures of the drawings.

IWill firstdescribe someA of' the general machine parts which are notnew herein but are well known in this type of machine. Thus the base Asupport-s a head A shown a hollow casting containing cams, ete., theupper portion of said head being formed into Va horizontally extendingarm A2 which overhangs the sewing position.

It should be explained that the work X, which maybe a piece ofleather,is supposed to be fed from the operator of a machine, that is toward theleft. in Figs. 2,'8 and 4, while the buttons served thereto bv means ofthe thread g/ ldrawn lfrom the usual spool or supply. A work support- BinglT or otherwise upheld so that the work may be pressed `netween thesupport B and the 'presser foot opposed thereto; and any desired meansmay he employed for causing the separation of the 'work supportv andpresser toot at the times that the work has 'mounted in a standard B mayhe .yieldhand oi the main shaft Z will he seen a pulley z, either looseor fast on. the shaft, adapt-- ed to he continuously driven when desiredby a pon-'er belt; also a handwheel z to facilitate manual operation ofthe main shaft, as will he well understood. Any ordinary clutchmechanism may be employed between pulley e and si aft Z, whereby theshaft may bedisconnected at will to render the machine id e. t#

ln the machine to which the 'present im- Y provemeuts are shown as aplied, the needle D is of the type having a ook instead of an eye, itpassing downwardly through the work from above to the point where thethread mechanism is locate and said hook serving to draw a loop upthrough the work and through the of the `button, or through apreviousloop as the' case may be. 'The needle D is shown secured at thelower end of a needle har D which is-fitted to slide vertically in thearm A2, and said neele may be reciprocated in any desired manner, as forexample through bell crank d', Fig. l, link l2 and arm d3, the latterhaving a pin which engages in the cam slot of a cam d* mounted on themain shaft Z. it will he understood that the Presser foot C isape-rtured or slotted ato which permits the passage of the needletherethrough, and also permits the line of vattached buttons to passalong'with vthe feeding of the Work.

For feeding along vthe work any convenient means may be employed, suchfor example as the feed prong shown in Patent 886,826 before mentioned;but as the Work feeding mechanism per se forms no part of the presentinvention, the mechanism thereof is omitted hercfrom. lt Will beunderstood, however, that the feed prong serves to feed the work an oneperiod a distance substantially equal to the space between two huttons,and at `mother period the comparatively slight distance between the twopunctures through which the loops extend for attaching a given button.

Any desired construction of thread handling mechanism may bc employed,and as that mechanism forms no part per se of the present invention, itis not completely shown; although a loopcr bar l" is indicated carryinga looper f at its upper end, the looper carrying the thread and beingadapted to' swing at proper times to carry the thread into the hook ofthe needle. The swinging of the looper bar and looper may he eiected bymechanism not shown, actuated by one of the cams on the main shaft. Z.

A loop spreader G is mounted and,l actu- Loeeee ated to coperate withthe other parte. The details of its fittings aud/actuating means will behereinafter described. Button feeding mechanism will he understood, andit will be of nature to feed buttons onel at a time into proper relationto the needle for the attachment successively of the buttons at spacedapart points on the work. For clearness the button feeding mechanism isentirely omitted.

The contour and therefore the timing of all of the cams herein shown anddescribed, will besuch as to cause the different instrumentalities toharmoniously coperatie for forming' the thread loops and locking themwith the buttons into attaching knots.

The mechanisms so far as above described are all known in the art and noclaim of novelty to them per se is made herein.

I will now describe the novel constructions and arrangements involved inthe present improvements, and will then explain their cooperation withthe other parts of the mchine. A cast-oil' employed in connection with ahooked needle in a machineV of the Vtype referred to, has severalfunctionsto perform. The cast-o` must move at times :in conjunction withthe needle, and at other times it must have movements rela-tively to theneedle. The cast-od must at times hold the` loop of thread in engagementwith the needles hook, and at other times it must effect the release ofthe loop. In attaching but-tons by a knot similar to that illustratedand described herein, the cast-olf also-has the function of holding openand away from the needle the first loop or bight of thread, While thesecond loop is pulled through the first loop. In performing thisfunction genorally, the cast-olf is caused to descend into contact withthe work, or even' to partially enter the puncture formed bythe needle.

It has been usual to arrange the needle bar and cast-off har in closeproximity to each other.I and heretofore the operation ol the cast-oli'has been effected hy connections formed between the two bars, theseconnections usually taking the form of projections engaging otherprojections or recesses, so that in their operation the two bars areintimately associated, and only the needle loar hais been actuated fromthe driving mechanism, the other taking its movements from vthe needlebar. With that type of mechanism there of necessity will occur suddenbumps and jars in the operation of the mechanism at those times -whenthe lugs come into mutual contact.- Other objections pertain to theheretofore employed mechanism. Thus in order that the cast-olf bar maynot at alltimes travel with the needle bar, a friction. device has hadto be employed, 'actingeon Vthe Vcast-off bar to hold it stationary'when hotactuated by the lugs i :hoeden which the needle might heoperated, and' also in the casteil movements; and the old type ofmechanism was subject to weer and breakage besides causing excessivevibration and noise such as to constitute a positive detriment.

An oh'ect of the niechenisni about to he describe is to overcome theabove chicotions, and in a broad sense Such mechanism for overcomingthose objections may stated to contemplate the combination withthefhookcd needle and the casteil located to'coperate therewith, oi'Aone cam for effecting the needle movements and another cam `foreifecting the casteil movements. It will he understood that' each of theroembers, is controlied in ni-.oveinents solely by its oivn com.

hand side Fig'. l, n short groove constituted v luy a pair ofprojections h2 horizontal and parallel to Ieach other. These are toreceive between them a roller if, as plainly seen in Fig. 7, said rollerbeing attached at theforward end of an oscillating erm h* Whose ree-rend fast on the horizontal shaft h5 which actuales it, Said shaft h5 hasits left end journeiled in a. projection .76 from the overhanging erinA, and its right-hand end in a standard 71.7 at vthe other end of theInachine. It is clear that oscillation of shaft h5 will eect ltheswinging of arm t and thereby upward and downward movements of theeast-od har and cast-oil.

A cern is proposed to be employed for causing the actuation of the partsjust described, although in using the term cam in this connection Iintend to include any equivalents therefor. The cam may operate througha groove thus bearing on both sides of its follower, o1' it may haveonlya single cam surface, in which latter case a spring should beemployed tokeep the followerin Contact with the cam. Such a spring ha isshown, it being for convenience in the form of a helix under tension,lattached at one end to a sleeve h" on shaft 71,5, and at the other ondto standard. 717. The tendency of the spring it? is torotate the shaft hin e 95 right-hond direction, Figs. 2, 3 and 4, and thereby lower thecasteil' har.

For opposingF the spring .its and raising the cest-oit' bar in thepropel? manner and at the proper times, cam J may 'oe employed, 100

located at any convenient point in the machine, for example directlyupon the .main shaft Z. The contour of the cam J is shown in l? and 4,each of which indicates it in a dilerent position. Bearing upon the 10.5cam .l is a roller j mountedv upon an' arm j", pivotedat to fixed partof the machine, and seid arm j has pivoted to it 'at-the point jfvlinllV i4 extending upwardly to an arm y" secured to the horizontalshaft h already referred to. By the connection described the am .l whenan eccentric portion comes into action. either raises or lowers theroller j, which acting' through arm j, link y" and nini j, effects anoscillation of shaft h5 115 which, as previously slated, is so connectedas to cil'cct the upward and downward Inovenients ot, the cast-oil" bar.

l will now describe4 my preferred relative and 'absoluto timing of thecams d* and J 120 which respectively actnote the needle bar end thecast-of har carrying the needle and the mst-oil respectively. Thediagram, Fig.

i', indicates the timing; ot` the nnufomonts the ifo-ll line dreprcsentinfv the i needle nim'einen s and the "itieggg the tuning oit'the 'the opper to the lower end ot the diagram n, complete cycle of movenie-nts is ropiwsentznl extei'iding from the 130 commencement ofoperation for aV given button until the complete attachment of thathutten to the work. From the upper to the.

lower end of the diagram it is divided into twenty portionsrepresent-ing equal intervals or units of time, the entire distance fromzero to 2U representing a compleie revolw tion of the main shaft Z. Thisdiagram will enable one skilled in the art to easily construct the camsfl* and J in accordance with my invention.

On analysis the diagram Fig. 9 shows the following operations to takeplace with re-,

spect to the needle and cast-ofi". The zero and 20 position is theinitial position of the machine While it is prepared to start upon theoperation of attaching a button, and this position is that which isillustrated in Figs. l and 2 of the drawing-s, the cast-off being at itshighest point and the needle being at a point slightly lower than itshighest point. From zero to 2 the line d passes from the right to theleft, this indicating a descent of the needle, and this portion of theline will be seen to be curved so as to give the most advantageousneedle dpscent. The needle will enter the Work between the points 1 and2, and it will be seen that be fore entering the work the needlesdescent is rapid, thus economizing in time, while'during penetration ofthe work the needles movement is less ,ra id and therefore of greaterpenetrating cree. This operation takes care of the natural slowing ofthe needle on meeting the resistance of the work, and at the saine timetheentire motion is a smooth one and calculated without need ofconsidering other conditions. During thc same period of time from zeroto 2, the cash ofi' 'isy seen to make an easy descent to the positionthat vit is to have upon the elevation of the needle. AFrom 2 to 3 theneedle and cast-off are stationary, this being the eriod when the looperis passing thread into the ncedies hook. Thereupon from lines 3 to 5 theneedle makes its complete ascent from lowest to Yhighest position.During this'ascent the needle bar does not require to operate upon lugson the cast-olia har, since the latter is independently taken care of asexplained. The cast-off 'when it in protectingy position upon the needles hook is slightly higher than the needlesl point and consequentlywhen the needle has nearly reached the height of .the cast-ofi asindicated at point 4, the cast-off must begin to rise, and its cameffects its elevation as shown, without shock or noise. From point 4to 5the needle and cast-oil' are rising at substantially the same speed,andat point 5 they both reach substantially thcirphighest positions. Atthis stage it will. be understood that a loop of thread has heen pulledup through the Work and'through the eye of 65 a button, said loop beingthen heid in eleoft Veasily and'ending up with vated position by theneedles hook, protected hy the cast-otf. From 5 to 6 the needle andcast-ofi" are stationary and duringr this time the work and button areshifted slightly from the operator so that on the next descent theneedle will pass outside of lthe buttons eye for making the secondpuncture. Thereupon the needle again makes a complete descent from pointG to point 7%, similar to its previous descent, and again puncturing thework. The needle reaches its lowest position and remains there untilpoint e diagram is reached, while another loop of thread is beingapplied to it. During this period from point 6 to point 8 or 9, thecastoff is also caused to descend, but its manner of descent is notrestricted by that of the needle, and the two curves of descent Thecast-offs descent is one commencing an easyand gradual motion so thatwhen tlie cast-off comes into Contact with the work no blow is struck,it on the contrary gradually and smoothly entering its position withinthe puncture in the Work. This stage of the operations is illustratedbyFig. 3, in which the needle is about to take a loop and the cast-olf isin contact with theiwork protecting the first loop from again engagingthe needles hook.. upon the needle commences to rise in advance of thecast-off, and it will rise until the hook iscovered by the east-off atpoint 9 of the diagram, the two thereafter rising in practical unisonuntil substantially the highest position of each has again been atAtained at point 10.1,A of the diagram. From this point .to point 12 ofthe diagram there is no movement of the needle and cast-oli. Fig. 4shows the position occupied` by them during this idle period. Duringthis -time the spreader G has begun to come into action to enter the.loop held conjointly by the needle and cast-off.

From and after the point 12 illustrated in Fig. 4, the cast-ofi" has nofunction, nor is it compelled to partake nt the nccdles movements, and astraight dotted line is therefore shown on the diagram from point l2 to20. The needle on the contrary is required to dip slightly, as indicatedfrom point 12 to 13 for the purpose of releasing the loop which thespreader has entered, so that thc spreader may then take charge of theloop and pass it oi'cr the button. Immediately after this dip orldescent of the needle, it rises again from point i3 to 14 tosubstantially its highest position and re-v mains there while the knotis being tightened and the Work fed forward to the position forattaching another button. As a .slighl economy in time, the descent ofthe needle for the suceeed'in button may hc caused to commence atpo1ntl8 of the diasoA 'will be seen to be substantially different.

It will be noticed that therelzo - view.

gram so that when point v20, which is the same as point -zero` has been'again reached, the needle will be already on its war down to enter theeye of the button.

From the above description it will now lbe clearly understood how themoiemcnts of the needle and cast-oli' are independently calculated" andeffected, and fromthe diagram lines d and h itwill be seen that the mostadvantageous, economical, easy` and silent mode of operation of both ofthe parts is secured withoutcontlict and in entire and perfect harmonywith each other.

It should lie-said that the type of l-not shown in the specificembodinient of the drawings hereof, is a well known one. A series ofknots are formed, each attaching its button, and each formed v'from acontinuous thread which is not required to be sev ered between knots.The first loop is carried through the work and then through the buttonseye, and held there temporarily while a, second loop is pulled throughthe work and` through the first loop. In pulling up the second loop itis customary to pull it so far as to cause a'tighteningtor takingA up ofthe first loop. 'The second loop is spread and placed over the head ofthe button. The thread mechanism then takes up the thread supply fortightening the-second loop and thereby, tightening the knot. While thespreader G may be of anyle; six'ed form, the following is riyprerferredform. Fig. 1 shows itin front View, Fig. 'left end view, and Fig. 8enlarged top The spreader is carried at the foot of al vertical axis orbar G which may be termed a s' reader bar, this bar being capable of suicient oscillation to swing the spreader into and out of spreadingposition. As Seen in Fig. 8 the spreader is not mounted directly 0nthe'bar G', but upon .gi short'axle contained in a. horizontal sleeve g,so that the spreader point g can be tipped over at the proper time forshedding the thread iloop. A clampy sleeve g2 serves to' hold thespreader `in place and also serves for the attachment lof a. spring g3,whosetendency is to hold the spreader 1n' horizontal position againsttipping. The spreader point g is at such a. distance from the spreaderbar G I that when the latter is swung the former will pass directlybetween the two strands of thread extending downwardly from the elevatedneedle, as clearly seen in Fig. 4.

For effecting the swln 'ng of thespreader and spreader bar, thetidllowing actua-ting mechanism maybe employed. Vl'necured at the upperend of the bar is a lever-g" extending toward the rear, :as seen in the)top viewgFig. 10, said lever` having at its outer enda roller g5whichengages inthe forked end of a lever g cehtr'ally piroted at f77.The lever g at its other end is pivoted at gs to a longitudinallyreciprocating the button. For effecting this tipping move- 'swungcompletely inward, the finger K' rod gn. The pivot g of the lever geissup ported on a stationary bracket g formed on or secured to the head3A* ot the machine, said bracket having the pivot y? atits rear end atthe lefthand of Fig. i', and formed at the other end to afford abeariugfor supporting the upper end ot' the spreader barA li. It isintendedthat the double lever g shall be oscillated by the reciprocatingrod y for the purpose Aof oscillating the spreader bar. To actuate theparts the said rod g is connected at its right-hand end,

Fig. l0. to a swinging arm gig, said arm y being shown also in dottedlines Fig. 2,

ithaving at its forward end a pivot 75 to 5o permit. its swinging.Fromfthe under side of lever g1 depends a. pin and roller gw,- Figs. 2and l0, which engages in the groove of cam g fixed to and rotatinwith-the main shaft Z. The contour oftie cam g is so timed as tocause'the'inward and outward swinging movements of the spreader at thetimes and in a manner that will be tunderstood from the precedingdescription of the machines operation.

'hen the spreader has been swung entirely inward carrying the secondloop with it to a point beyond that shown iu'Fig. 4, vthe spreader isthen required to tip downwardly and shed th loop over the head of ment,a finger or projection K is provided on the spreader, it bing moreclearly shown in Fig. 8. When the spreader vhas been comes beneath theend .7.: of a swinging arm le', pivoted at k2 to a fixed lug Ic. At theother end of arm lc is a pivotaloonnection ki to an upwardly extendinglink k, see Fig. 2, the upper end of said link being pivotally connectedto an arm is", secufredto an auxiliary shaft In?, Figs. l and 10. Theshaft kf extends'. from left to "right and at its right end passesthrough journal les to where at its extremity it has secured to itan armk"- extending downwardly and to the rear, where it carries a roller k1,Figs2 and 10. Said roller 7cm .engages with a cam le mounted on theshaft Z. The roller merely bears upon the cam which is generallycircular but has an eccentric or projecting portion lets. When theportion klacomes into position beneath-the roller ZEP, it lifts-and thendrops the roller so as to cause the tipping and then the restoration ofthe spreader' as described. In order to hold the roller je in lcontactwith its operating cam a springA lf2, Fig. 2, may be employed, it'heingshown secured at one end to the arm 7c carrying the roller, and at itsother end to 'a lixed part. 125 of the machine frame.

In Fig. the needle is about. tomove vertically upward for forrning the seo-ond loop.' ln Fig. 4 theneedle in upward position and the point g of the Spreader is enteringthe loop for the p'iirpose vof spreading it' preparatory to shedding itVover the button.v In Fig. 3 lthe needle son ..norter Mis in idleEositon.

To adapt it for this the "supportervpivoted sito; to the merhunglngu arm A2 mesme over, it is shown ashaving come into needle supporting position so as to firmly back up theneedle during the operation of the spreader. From this ligure theutility of the device will be plainly seen. The button is slightly totherear of tbe needle so that the loop stands at an incline. 'The spreaderin entering the loop puts the thread under heavy tension, thus Causinga. side strain on the needle. and moreover the spreaders movementis onetoward the rea-r, lthus increasing the strain and the tendency toVdefleet the needle rearwardly. Such deflection, however, is entirelyprevented by tlienddi- 4tionel strength and support given to the' needleby the supporter M.
